While there's no word yet on when Paltrow will film her episode or when it will air, it's safe to say her first appearance — during which she made fun ofLindsay Lohan, rapped to Cee-Lo's "F—k You" and sang in the rain — turned her into a total Gleek.

"My kids came out [to the set] and my daughter fell in love with Heather [Morris] who plays Brittany and whenever she sees a Glee thing she's like, 'It's Heather!' and her friends are like 'What?'" says the actress. "I'm like, 'Oh God, let's not explain.'"

"There is nothing she can't do! She sings, she dances, she acts," enthused Lynch, who appears on the high school song and dance series as cheerleading coach Sue Sylvester. "She is funny and a great mom and a good person!"
